Abstract

A procedure to study tracer dispersion was proposed and tested for the case of tracer spreading in tube flow. Concentration maps of paramagnetic tracers Gd3+ were measured in time through direct measurements of spin lattice relaxation time T1 obtained by using a two-point stimulated echo pulse sequence. The procedure was used to test the linear dependence of Peclet number on inverse velocity in the range of flow rates 0.3-1.2 cc/min.
